I don’t see anything change other the initial red light that turns on when i start to charge - that goes out after a while. Is there a fully charged indicator?
You get a “battery high” audible when you power them on to indicate full.
When connected you see battery level on your phone.
The manual shows red when low, white when full.
You can also see it in the Soundcore app when you pair to it but when charging up is usually go by the little light on the bottom
Nice pic, @professor.
But why are head phones crying
